1. A golf ball, comprising: a molded core comprising a high cis-polybutadiene having a Mooney viscosity of from about 20 to about 70 and an Instron compression of greater than 0.0880; a mantle comprising a highly neutralized ionomer and a fatty acid, the mantle having a Shore D hardness of from about 30 to about 85; and and a cover composed of a high flexural modulus ionomer material; wherein the golf ball has a diameter of at least 1.68 inches.

2. The golf ball of claim 1, wherein the core has a COR of from about 0.600 to about 0.850.

3. The golf ball of claim 2 wherein the core further comprises a peptizer.

4. The golf ball of claim 3 wherein the core further comprises a metal thiosulfate.

5. The golf ball of claim 3 wherein the peptizer is pentachlorothiophenol or a metallic salt thereof.

6. The golf ball of claim 4 wherein the metal thiosulfate is disodium hexamethylene thiosulfate dihydrate.

7. The golf ball of claim 1 wherein the highly neutralized ionomer of the mantle is neutralized to about 90% or more.

8. The golf ball of claim 1 wherein the highly neutralized ionomer of the mantle is neutralized to about 100%.

9. The golf ball of claim 1 wherein the fatty acid is stearic acid, oleic acid, a metal stearate, or a metal oleate.

10. A golf ball, comprising: a molded core comprising a high cis-polybutadiene having a Mooney viscosity of from about 20 to about 70 and an Instron compression of greater than 0.0880; a mantle comprising an HPF material, the mantle having a Shore D hardness of from about 30 to about 85; and and a cover composed of an ionomer material.

11. A golf ball, comprising: a molded core comprising a high cis-polybutadiene having a Mooney viscosity of from about 20 to about 70 and an Instron compression of greater than 0.0880; a mantle comprising an ionomer neutralized to 80% or more and a fatty acid, the mantle having a Shore D hardness of from about 30 to about 85; and and a cover composed of an ionomer material.

12. A golf ball, comprising: a molded core comprising a high cis-polybutadiene, pentachlorothiophenol or a metallic salt thereof, and an optional disodium hexamethylene thiosulfate dehydrate; a mantle comprising an ionomer neutralized to 80% or more and a fatty acid, the mantle having a Shore D hardness of from about 30 to about 85; and and a cover composed of an ionomer material.
